drm/xe/guc: Enable w/a 14022293748 and 22019794406
Enable workarounds for HW bug where render engine reset fails. Given
that we're bumping the minimum required GuC version to 70.29, we're
guaranteed to always have support for this KLV in the GuC.
v2: Enable KLV correctly for either workaround (Lucas)
v4: Add check for minimum supported GuC firmware version. Enable w/a for
hw version 20.01 too. (Daniele)
v5 (Daniele): remove now unneeded fw type and version checks (JohnH)
